It is very important that ,the D offical should make an investigation. For example, why does'd attract you? What are the 'defects' of other language? How would you like 'd' to serve you?

For me, some metaprogramming functions of c++ is not as cool as d.I hope that the d language can better link to my previous C++ library.

Wrong, I didn't give up fast. Just comfort and safety first!
In other words, I like writing code very comfortable.
Like 'c++', every time at the end, I have to use macros. That feeling, you know?

Why don't you like 'rust'.
when you see the full screen ::,do you have a good impression?
Therefore, I hope that d's ecology can grow up.
D need to know, who do you serve, Big company? No!
D should not serve for big company. On the contrary, d should serve for programmers and top programmers first, and make them happy. This is my view of d's reasonable positioning.

I also hope that d can have ... operator.
It turns out that 'manu' has a 'dip', which is obviously a good thing. Why not add it?
D need to learn 'c++''s success.Add when you should.As long as no use, no cost. Then who cares.
As for d's becoming complex , which successful language is not complex in the end?
I just hope that I can configure like 'vim',Everything is configurable.

Rarely used features makes code difficult to read.

I think languages get popular when they are simple enough, but not lacking. Then many languages keep adding stuff when they no longer grow, because they cater to people who already master it. As a result they become less accessible to beginners and maybe the next generation of programmers goes elseswhere.

It is important for small languages to avoid complexity and not overfocus on the demands of the hardcore users. Unlike big languages they totally depend on being accessible to beginners.

Hard to read? No, it is very cool. You don't need 'for/foreach' at all!
There are so many problems to be solved that simplicity must become complicated.

C++ now has corotine and is more complicated, but who cares.
The important thing is to 'solve the problem', the important thing is 'cool'!

If language wants to attract top programmers, it must meet the needs of them.

As long as the feature is satisfied, and there is no cost if it is not used .
No one 'cares' about adding new features.
The more features, the better, as long as they meet the needs of top programmers!
Why do beginners know so much,learning while using like vim.

The library author is the most important.
And excellent programmers are the core competitiveness for a language.

I think c++ needed this because it does not have a no-scope (static) foreach.
On the other side our unscoped foreach implementation is known to have limits.

This is not 'static foreach', it is folding expr. If you've written it, you know it's very cool.

template<class...T>int f(char c,T&&...t){
    return b(c,t...)+c;

yes you're right when you suggest that I've never used it.

My point was actually more on the fact that "..." solves the fact that c++
foreach does not work on tuples, i.e aggregates made of different types, while D has static foreach, which can be similarly used let's say to unroll += on each member of a tuple.
